Repeating watermark php - php

Question

I am using Intervention Image image manipulation library this library in a project and I am stuck on adding watermark image all over the source image.
Is it possible to repeat the watermark image on all over the source image like in the following example?
I try the following code, but it doesn't work for me.
$thumbnail = $manager->make($name);
$watermark = $manager->make($watermarkSource);
$x = 0;
while ($x < $thumbnail->width()) {
$y = 0;
while($y < $thumbnail->height()) {
$thumbnail->insert($watermarkSource, 'top-left', $x, $y);
$y += $watermark->height();
}
$x += $watermark->width();
}
$thumbnail->save($name, 80);

I've just solved this problem via Intervention Image library using it in Laravel Framework. So here's code snippet.
public function watermarkPhoto(String $originalFilePath,String $filePath2Save ){
$watermark_path='photos/watermark.png';
if(\File::exists($watermark_path)){
$watermarkImg=Image::make($watermark_path);
$img=Image::make($originalFilePath);
$wmarkWidth=$watermarkImg->width();
$wmarkHeight=$watermarkImg->height();
$imgWidth=$img->width();
$imgHeight=$img->height();
$x=0;
$y=0;
while($y<=$imgHeight){
$img->insert($watermark_path,'top-left',$x,$y);
$x+=$wmarkWidth;
if($x>=$imgWidth){
$x=0;
$y+=$wmarkHeight;
}
}
$img->save($filePath2Save);
$watermarkImg->destroy();
$img->destroy(); // to free memory in case you have a lot of images to be processed
}
return $filePath2Save;
}
If you use PHP version prior to 7 remove String type declaration from function arguments. just make it
public function watermarkPhoto($originalFilePath, $filePath2Save ){....}
Also if you are not using Laravel Framework and you don't have File class included just remove redundand check from function.
if(\File::exists($watermark_path))
So the simplest framework-agnostic function would be:
function watermarkPhoto($originalFilePath, $filePath2Save ){
$watermark_path='photos/watermark.png';
$watermarkImg=Image::make($watermark_path);
$img=Image::make($originalFilePath);
$wmarkWidth=$watermarkImg->width();
$wmarkHeight=$watermarkImg->height();
$imgWidth=$img->width();
$imgHeight=$img->height();
$x=0;
$y=0;
while($y<=$imgHeight){
$img->insert($watermark_path,'top-left',$x,$y);
$x+=$wmarkWidth;
if($x>=$imgWidth){
$x=0;
$y+=$wmarkHeight;
}
}
$img->save($filePath2Save);
$watermarkImg->destroy();
$img->destroy();
return $filePath2Save;
}
Also you need watermark image in png format with transparent background.

I'm just adding one thing added to your accepted answer when you try your code and the above-accepted code, the watermark on the images will be very close together and close together with what I tried. like this
So if you want the watermarks like what you want, you need to modify the code with plus numbers on wmarkheight and wmarkwidth like this:
while ($x < $imgWidth) {
$y = 0;
while($y < $imgHeight) {
$imgFileCollection->insert($watermark, 'top-left', $x, $y);
$y += $wmarkHeight+30;
}
$x += $wmarkWidth+40;
}
this line of code is important:
$y += $wmarkHeight+30;
$x += $wmarkWidth+40;
and you will get the result like that below:
